How this list was made
We pulled 225 Tucson-area water treatment companies from Google Maps, then kept the 25 with a rating of 4.0 or higher and at least 10 reviews. The average rating in this group is 4.85 stars.
Ratings with only a few reviews are pulled toward that average, so a business needs a real track record to reach the top. Nobody pays to be here. Read the full method.

We started with 225 Tucson-area businesses from Google Maps and kept the 25 with at least a 4.0 star rating and 10 or more reviews. Each rating is then weighted by how many reviews back it up, so a perfect score from a handful of reviews does not outrank a near-perfect score from hundreds.

No. Positions come only from public Google ratings and review volume. Claiming or updating a listing is free and does not change its rank.
